[1] Ecosystem types within the Park include lowland and highland forests, with flora such as Gutta-percha, Shorea, Alstonia scholaris, Dyera costulata, Koompassia excelsa, Rafflesia hasseltii, Calamus draco , and various other kinds of rattan.

As the result of research, the Bukit Tigapuluh ecosystem with an area of 250,000 ha was recommended to be determined as a national park.

[1] Surrounding buffer zones and wildlife corridors are diminishing, with 30,000 hectares, the largest area of forest remaining outside the Park, released in May 2009 by the Indonesian government for logging.

The first reintroduction station for orangutans close to the park was built in 2001 by the German biologist Dr. Peter Pratje, with the support of the Frankfurt Zoological Society and local partners.

[6][7] Camera traps set up in the Bukit Tigapuluh forest in March and April 2011 by the World Wildlife Fund (WWF) have taken images of 12 rare Sumatran tigers, including a mother playing with cubs.

[8][9] None of the Bukit Tigapuluh landscape is covered by the moratorium and Asia Pulp & Paper plans to clear large areas of the forest.
